I don't need to know this about your child! As a teacher, what would I say if he came to school in this shirt? I know, nothing here is offensive, or perverted, or sexual....but still. It's one thing to share your beliefs when someone asks for them, but it's another thing to use your children to spread the word. How is another little boy who was formula fed, stroller stuffed, solitary slept, and circumcised going to feel? Unlucky? How will his mother feel? That might depend on if she cared about those things, but even if she hadn't cared one way or the other about co-sleeping or formula, etc, she still did what she felt was the right thing for her and this shirt implies that all other types of parenting are wrong and perhaps even damaging.
What I would love to see is a shirt that says "Ask my Momma why I'm so lucky" or "Ask my Momma how you can have a great babe like me!"
